It definitely isn't on very snug like that at all. I can turn it about 2-3 inches to the left and right without my skin/face turning. The Bell doesn't have larger cheek pads unfortunately. I'm thinking that this will break in and become even more loose.
Definitely too large then.
I tried on a Stilo helmet in large and it was just way too big. When I tried the medium, it was so tight that I didn't think it would ever break in enough, so I didn't buy it. Sometimes you have the misfortune of falling between sizes for a particular brand, in which case, you have to move on. I ended up with an Arai for this reason.
